Abstract: This study was carried out to determine the effect of Alphagen Standart Prill (ASP) which was used in pellet form by mixing with litter in nest box on microorganism counts of egg shell surface and hatching results. In the experiment, hatching eggs of broiler parent stocks Cobb-500 from 40-43 week old were used. The total bacteria, coliform bacteria and E.Coli counts were significantly different between experimental groups ( 0 (control), 5 g, and 8 ASP/nest box) (P<0.01). The hatchability of fertile eggs was not different in treatment groups (90.39 %, 90.12 % , 91.32 %, respectively by groups, P>0.05). The hatchability of total eggs was 88.54 % in 8 g ASP/nest box treatment which was higher than those of control ( % 87.80) and 5 g ASP/nest box groups (% 86.79) without statistical significance (P>0.05). According to the results, embryonic mortality at early (0-7. day), middle (8-18. day) and late (19-21. day) period of incubation was not changed by treatments (P>0.05). However, the rate of early, middle and late mortalities was 3.62, 3.50 and 3.57 % for 5 g ASP treatment, 0.02, 0.10 and 0.9 % for 8 g ASP treatment and 2.63, 2.27 and 3.01 % in control, respectively.
